Workers at a Rolls-Royce engineering factory are to stage a one-day strike next week after peace talks collapsed.
The walkout at the Ansty plant near Coventry in England next Friday is in protest at plans to cut jobs and transfer some work to Canada.
The Manufacturing Science and Finance union says workers are being forced to take industrial action.
"We will work to avoid a strike, but we need the company to show that it is willing to listen by withdrawing redundancy notices and entering into constructive talks," said general secretary Roger Lyons.
The strike will be the first at the plant in more than 20 years.
